MARCI weather report, February 20-26, 2017

A major dust storm system traveled down the Acidalia storm-track this past week on Mars. Two dust storms observed at the beginning of the week, quickly merged, forming a regional dust storm. The regional dust storm was further fed by subsequent dust lifting over Acidalia. At the middle of the week, the storm swept east and west affecting Lunae Planum and western Arabia. By the following sol, a regional scale dust storm also cropped up over the Solis-Sinai region. Furthermore, this storm merged with the major storm and propagated southwest over Aonia and eastern Daedalia. The eastern extents of the major storm stretched over Argyre and western Noachis as well.
